Denatured alcohol containing quinoline



Patented Nov. 14, 1939 STATES PATENT OFFER DENATURED ALCOHOL CONTAININGQUINOLINE No Drawing. Application October 14, 1937, Serial No. 168,972

1 Claim.

This invention relates to the denaturing of ethyl alcohol, and toalcohol so denatured.

It is an object of my invention to provide a denaturant which willrender ethyl alcohol containing it unfit for use as a beverage, whichcannot be economically removed from the alcohol by any known methods,which will not render the alcohol unfit for industrial uses in whichdenatured alcohol has customarily been employed, and which will be freefrom methanol. Other objects will hereinafter appear.

I have discovered that quinoline is an effective denaturant for alcohol.In denaturing ethyl alcohol with my novel denaturant, I may use from 0.5to 5 parts of quinoline, or even more, per 100 parts of 95% alcohol.Quinoline may be used alone in denaturing, or it may be used inconjunction with lower aliphatic ketones, or with chloroform, or withany other denaturants with which it may be found to be compatible. Whenquinoline is used. with chloroform, I prefer to use approximately equalparts of chloroform and quinoline. From 0.5 to 5 parts, or even more, ofany of the combinations may be used, per 100 parts of 95% alcohol.

What I claim as my invention, and desire to be secured by Letters Patentof the United States is:

Industrial ethyl alcohol denatured with 0.5 to 5 parts of quinoline, asan essential denaturing element, per 100 parts of 95% ethyl alcohol.
